All specifications apply filter soldered to the RFM specified demonstration board with impedance matching to 50
network analyzer.
Unless noted otherwise, all frequency specifications are referenced to the nominal center frequency, fc.
Rejection is measured as attenuation below the minimum IL point in the passband. Rejection in final user application is dependent on PCB layout
and external impedance matching design. See Application Note No. 42 for details.
Part to part absolute delay measurement records the absolute delay mean across 1dB passband.
“LRIP” or “L” after the part number indicates “low rate initial production” and “ENG” or “E” indicates “engineering prototypes.”
The design, manufacturing process, and specifications of this filter are subject to change.
Either Port 1 or Port 2 may be used for either input or output in the design. However, impedances and impedance matching may vary between
Port 1 and Port 2, so that the filter must always be installed in one direction per the circuit design.
US and international patents may apply.
